Changeset 385 for trunk/game/objects/buildings/shanty

Patch by mvbarracuda:

• Removed shanty building as it featured a wrong scale, no source version is available to rerender it and it's not clear if any 3rd party textures are used and how they are licensed; the modeler who created the building is not active anymore
• Removed windmill test object; too small and odd looking white outlines
• Moved metal box into the proper folder
